Atrial fibrillation (AFib) with rapid ventricular response is a heart rhythm disturbance that puts you at higher risk for stroke and other serious complications. There are treatment options. Share on ...

In tracing "a" of Figure 1, there seems to be only one P wave in front of each QRS complex, suggesting sinus rhythm. However, during the compensatory pauses after the PVCs (↑) in tracing "b," there ...

Peter Spector, M.D.; Nicole Habel, M.D. iii Shorthand convention meaning "advances the timing of the subsequent atrial activation." iv Delivered during His refractoriness v The conclusions that we are ...

In the last few weeks, the Skeptical Cardiologist has had a run on with patients with premature atrial contractions (PACs). I've discussed in detail premature ventricular contractions (PVCs) here and ...

Palpitations due to premature beats, either ventricular contractions (PVCs) or atrial contractions (PACs), can be extremely vexing even when we know they are benign. For many individuals, these ...

Atrial fibrillation (AFib) is a disorder centered in the heart's upper chambers that causes the organ to be unable to maintain its regular rhythm. The condition can cause palpitations, fatigue, ...

Philadelphia, October 12, 2022 – Extended cardiac monitoring in patients and the use of implantable cardiovascular electronic devices can increase detection of atrial fibrillation (AF), but the ...

Philadelphia, PA, Oct. 27, 2017 - Recent studies have determined that blacks have a lower risk of atrial fibrillation (AF) compared with whites despite having a higher prevalence of risk factors such ...

Atrial fibrillation with rapid ventricular response is a fancy name for an irregular heartbeat. When your heart's electrical signals aren't working right, it can lead to a heartbeat that's too fast.
